The right to education, recognized and protected globally, serves as a vital catalyst for marginalized individuals—both adults and children—to escape poverty and actively engage in their communities. It empowers women, shields children from exploitation, upholds human rights, fosters democracy, and contributes to environmental preservation. Education, a fundamental human right, intertwines with other rights, shaping the full development of individuals and promoting global understanding. Despite its critical role, challenges persist in ensuring universal access to basic education, emphasizing the urgency of addressing this issue for a more equitable society. Despite the right to education being a cornerstone of human rights, marginalized and vulnerable groups struggle to obtain quality education. This paper dissects legal frameworks guaranteeing this right, particularly how they can be utilized to ensure access and quality for these populations. The paper explores international and national legal instruments recognizing the right to education. It then delves into the challenges faced by marginalized groups, including geographic isolation, poverty, discrimination, and disabilities. The core analysis focuses on legal strategies to overcome these barriers, such as litigation, policy reform advocacy, and leveraging human rights mechanisms. By examining successful legal tactics, this paper aims to provide a blueprint for promoting accessible and high-quality education for all. This includes fostering inclusive learning environments, culturally relevant teaching methods, and addressing the specific needs of marginalized groups. Ultimately, the goal is to contribute to a more equitable and just education system that empowers everyone to reach their full potential.
